Next, the operation in case of settling the oil supply charge in cash will be specifically described with reference to FIG. 3 and FIG. 6.

At first, in order to settle the oil supply charge in cash, in the change payer 30, if the clients insert the bill into the bill processor 31 or insert the coin in the coin processor 32 and subsequently, if the manual operation button 33 is pushed, a signal (A) indicating money insertion is transmitted to the POS terminal 50 from the change controller 35 via the signal line 23. Receiving this signal (A) indicating money insertion, the POS terminal 50 transmits a signal (B) indicating a switching of an image frame switched to the oil supply setup controller 45 via the signal line 24. When the oil supply setup apparatus 40 receives this signal (B) indicating the switching of an image frame, for example, the cash indicating image frame as shown in FIG. 10 is indicated on the touch panel indicator 43. If the confirmation button on this cash indicating image frame is pushed, a signal (C) for confirmation of cash insertion as shown in FIG. 10 is transmitted from the oil supply setup apparatus 40 to the POS terminal 50 via the signal line 24. Next, receiving the signal (C) for confirmation of cash insertion, the POS terminal 50 transmits a signal (D) for money insertion request to the change controller 35 via the signal line 23. For example, in case of supplying the hi-octane gasoline amounting to 3,000 yen, if the money 5,000 yen is inserted, a signal (E) showing that the money amount 5,000 yen is inserted is transmitted to the POS terminal 50 via the signal line 23. In addition, on the money amount indicator 34 of the change payer 30, this is indicated as a deposit 5,000 yen, and at the same time, on the touch panel indicator 43 of the oil supply setup apparatus 40, this is indicated as the deposit 5,000 yen as shown in FIG. 11. Subsequently, by pushing a desired button for a oil supply as shown in FIGS. 11 to 16, a signal (G) set by the operation to the POS terminal 50 is outputted, and determining the signal, the POS terminal 50 outputs a signal (F) for a switching of an image frame to the oil supply setup apparatus 40. Pushing the confirmation button in FIG. 16, the last signal (G) is outputted to the POS terminal 50 and a signal (H) for allowing the oil supply is transmitted to the oil supply controller 20 via the signal line 22. Further, as shown in FIG. 17, taking off the indicated predetermined oil supply nozzle 13 from the nozzle hanger 14, the nozzle switch 17 is turned on to start the oil supply. Then, a signal (I) indicating the oil supplying state including the oil supply quantity measured by the flow meter 18 is transmitted to the POS terminal 50 via the signal line 22, and as shown in FIG. 18, the image frame is switched. In addition, if the hi-octane gasoline attains to the set amount such as 3,000 yen or the like and the nozzle switch 17 is turned off, an oil supply finishing signal (J) is transmitted from the supply controller 20 to the POS terminal 50 via the signal line 22. Receiving this oil supply finishing signal (J), the POS terminal 50 transmits a signal (K) for a switching of an image frame showing the end of the oil supply to the oil supply setup controller 45. Receiving this signal (K) for a switching of the image frame showing the end of the oil supply, the oil supply setup apparatus 40 issues the receipt of the settlement of the oil supply by the receipt issuing machine 44 with the image frame switched as shown in FIG. 19. Subsequently, the POS terminal 50 transmits a signal (L) for instructing the change disbursement to the change controller 35 when the change is needed.

Next, the disbursement operation of the change of the change payer 30 will be described below. FIG. 6 is an exemplary illustration of the operation based on a signal in the oil supplying state and the money disbursement operation of the change payer 30. The change payer 30 makes the shift to a waiting time till the disbursement process is completed (time when there is a plurality of oil supply apparatus 10 at the oil supply station and the POS terminal 50 outputs a signal for instructing the change disbursement to each oil supply apparatus 10) after the end of the oil supply (namely, the nozzle switch 17 is turned off). If there is no need of the change, the POS terminal 50 receives the signal in the oil supplying state from the oil supply controller 20 so that the change payer 30 makes the shift to an idling state after lapse of a certain time. In other words 14 is transmitted a signal for a temporal stop of the oil supply to be continued till the oil supply nozzle 13 is hung on the nozzle hanger. In FIG. 6, this signal is turned on during the oil supplying and when the oil supply is temporally stopped, this signal repeats on and off at certain intervals of 0.5 second, for example. The change payer 30 receives an off signal of the nozzle switch 17 and the disbursement instruction becomes in the waiting condition to wait for a signal for instructing the change disbursement. Receiving the signal for instructing the change disbursement, the POS terminal 50 returns to the idling state after the completion of the disbursement. In addition, not receiving a signal (L) for instructing the change disbursement, the change payer 30 determines that there is no need of the change and shifts to the idling state when a waiting time, for example ten seconds, during the disbursement has been processed.

In the oil supply apparatus 10 of a self-service system configured as described above provided with the change payer 30 and the oil supply setup apparatus 40 to settle the oil supply change in cash, the clients inserts the cash in the bill processor 31 and the coin processor 32 in accordance with the instruction image frame indicated on the touch panel indicator 43 provided to the oil supply setup apparatus 40. In addition, setting the content of the oil supply such as the oil type and the oil supply quantity or the like and taking off the oil supply nozzle 13 from the nozzle hanger 14, the oil supply has been started. After a certain oil supply, if the oil supply nozzle 13 is hung on the nozzle hanger 14 and if the change is needed, the change is disbursed from the bill processor 31 or the coin processor 32 of the change payer 30 after lapse of a certain time. Accordingly, the clients can easily perform a cash transaction on site in cash after the completion of the oil supply even if the clients enjoy the oil supply service in cash.
